Provannidae is a family of deep water sea snails, marine gastropod mollusks in the superfmaily Abyssochrysoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005 and updated in 2008 by Kaim et al.).[3]

Pseudonininae Bertolaso & Palazzi, 1994

The genera Provanna and Desbruyeresia have smaller and slender shells, while the shells of Alviniconcha and Ifremeria are larger and swollen. The shells of these two last genera house a hypertrophied ctenidium large quantities of symbiotic bacteria.

Habitat edit

These snails are part of the fauna of the deep-sea hydrothermal vents, cold seeps, whale falls, and sunken driftwood environments.[4]

Taxonomy edit

The family Provaniidae was previously placed in the "Zygopleuroid group" (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). This family has no subfamilies according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005.

Subsequently, Provaniidae was placed in the superfamily Abyssochrysoidea Tomlin, 1927.[1]

There are some affinities with the Littorinoidea as shown by molecular data [5] and sperm ultrastructure [6]

Multi-gene analysis has shown that the family Provannidae is paraphyletic. It is being treated as belonging to the superfamily Abyssochrysoidea until a new family-level revision has been undertaken.[7]

Genera edit

Genera within the family Provannidae include:
